Biotechnology has also provided us with a remarkable technique in the form of immobilized enzyme systems, which allowed the production of a variety of substances e.g. production of high-fructose corn syrup (as a sweetening agent for soft drink industry) using an immobilized enzyme, glucose isomerase.

The market for these immobilized enzymes now is of the order of billions of dollars per year and supports multibillion dollar industries, because the cost involved in the production of these enzyme systems is only a fraction of the value of the products manufactured.
